Kaustubha Raghukumar, Ph.D.

Senior Consultant

Dr. Kaustubha Raghukumar is an oceanographer with a solid background in physical oceanography, ocean acoustics, and wave propagation physics, and has authored a number of peer-reviewed scientific papers in this area. He has 15 years of experience in modeling and at-sea measurements of hydrodynamic processes, such as ocean circulation, surface waves, internal waves, and underwater sound. He has participated in several international at-sea experiments that focused on the impact of oceanographic fluctuations on ocean acoustic propagation, and he continues to develop state-of-the-art acoustic monitoring techniques and technologies for the U.S. Department of Energy and the Office of Naval Rese...

Oceanography

Offshore Wind and Upwelling, California Energy Commission Served as technical lead for an atmosphere-ocean modeling effort to understand the effect of energy extraction by floating offshore wind turbines on coastal upwelling.
Measurement Buoy Development, Advanced Research Projects Agency – Energy Developed algorithms and performed field validation for a low-cost wave measurement buoy, the Spotter, developed by Spoondrift, Integral, and Sandia National Laboratories.
Matilija Dam Removal, California Developed nearshore, phase-resolved wave models to accurately advect expected sediment loads following the removal of the Matilija Dam on the Ventura River and inform long-term shoreline change.
Vandenberg Unexploded Ordnance Study, Point Sal, Central California Led a 3-month field effort to examine the long-term fate and transport of unexploded munitions under the influence of physical forcing, such as waves and currents.

R&D

Optical Imaging of Ensonified Ocean Waves, Office of Naval Research Acted as technical lead to characterize surface gravity capillary waves induced by underwater acoustic fields with the goal of achieving rapid bathymetric mapping via in-air acoustic sources.
NoiseSpotter, U.S. Department of Energy Lead the development of a vector sensor array with real-time telemetry to monitor the acoustic output of marine renewable energy devices, ultimately to help abate risk associated with sound from marine renewable energy installations.
Inner Shelf Direct Research Initiative, Office of Naval Research Performed experimental design, field efforts, and data analysis to characterize transmission loss in the surf zone and to examine the effect of bubble plumes in attenuating sound.

Ecological Modeling

Ecosystem Model, MEGAMER Facility, University of California, Santa Cruz Implemented a coupled ecosystem model (ROMS) of the California Current System and studied the biological impact of assimilating physical oceanographic data. Proposed a simple method to mitigate the deleterious effects of physical data assimilation while simultaneously preserving improvements following data assimilation.
